Editing sequences

whats up. i just picked up a 2500, my first mpc. when your editing a sequence is there a way to copy the events from tracks to the added bars but only copy some tracks and not all the tracks in that bar. Also when after i get so far and i change it up for the hook, do you's usually just keep goin on that sequence or start a new sequence and put it together in the "song" feature. i'm used to doing all my editing right on digital performer and i want to learn how to do it on the mpc to see which is easier/quicker to use. Thanks

you just answered your own question. read the manual. use the search function on this site. play around with your new toy and find your way.
